Shawn Corvec Skew-T Explorer Every weather-balloon (radiosonde) sounding ever released, anywhere on Earth, back nine decades. Blue stations have a launch in the last 36 h at high resolution; teal are active, red are closed (archive only). Click a station, then pick Latest or Archive and a date. Recent launches load instantly; the first click on a station can take a few seconds to load, or longer for archived data which has to be downloaded (older soundings come from NOAA's global archive as one big per-station file, with a pulsing note showing progress) — then every other date at that station is instant. The full analysis — parcels, CAPE, shear, hodograph — runs entirely in your browser via SHARPlib compiled to WebAssembly. ← HOME

Data: latest soundings from the University of Wyoming archive (BUFR, mirrored ~4×/day — UW sends no CORS headers); any historical date directly from NOAA IGRA v2 (first load per station can be tens of MB, then cached). Analysis: SHARPlib (K. Halbert, NWS SPC lineage) as WebAssembly — SB/ML/MU parcels, LI, DCAPE, effective inflow, Bunkers, SRH, effective shear, SCP/STP. Map: Leaflet & OpenStreetMap.
